Abstract

BECAUSE of its physiological importance, allosteric properties and ready availability, D-glyceraldehyde-3-phosphate dehydrogenase (G3PDH) is one of the most thoroughly studied of the dehydrogenases. We report here a study of the ligand binding properties of G3PDH. We observed that when active site carboxymethylated G3PDH was irradiated with near ultraviolet light in the presence of NAD+, a new fluorophore was formed.
